This has become one of our favorite things lately when we don’t have the time to sit down and enjoy a pot of tea. We just throw two of Runa’s Guayusa spice satchets (whatever, they’re good) into each libre glass and add boiling water. It only takes 2 minutes to steep, and you can take it anywhere. When the highly-caffeinated travel pouches of guayusa meet the highly-portable Libre glass, it’s a magical thing.
